A separation structure (1) for isolating a delimited space (B) from the external environment (A), in particular a space (B) defined by an apparatus operating in the pharmaceutical material processing sector, comprises suitably assembled separator means (2, 3, 4) of the panel type or the like and seal means (G) inserted between the separator means (2, 3, 4); the seal means (G) being of the fluid dynamic expansion type and formed by at least two separately expanding tubular ducts (6, 8; 1:3, 14; 5, 5'); in each of the two tubular ducts (6, 8; 13, 14; 5, 5') the supply of a pressurised or, if selected, negative pressure fluid being designed to be activated to cause the duct (6, 8; 13, 14; 5, 5') to expand or contract.
